A fire at a Rosneft-owned export-oriented oil refinery in the southern Russian town of Tuapse overnight has been extinguished, local officials said early on Thursday, Ednews reports citing Reuters.
The refinery is one of many energy infrastructure facilities hit by fire or drone attacks across Russia in the past week.
"The vacuum unit was on fire. According to preliminary information, there were neither casualties nor injured," Sergei Boiko, the head of Tuapse district, said on the Telegram messaging app.
The plant's annual capacity is 12 million metric tons (240,000 barrels per day). It supplies fuel mainly to Türkiye, China, Malaysia and Singapore. The plant produces naphtha, fuel oil, vacuum gasoil and high-sulphur diesel.
The cause of the blaze and the scale of the damage were not immediately clear. A Rosneft representative was not immediately available for comment.
Unofficial Telegram channels showed pictures of the blaze and said drones had been responsible.
